The present invention relates to shoe heel clamps and has mainapplication in connection with wooden heels, in womens shoes, the objectbeing to retain the wooden heel while i the leather layer is nailedthereto to prevent splitting of the wooden heel during the process ofdriving nails therein.

A further object of the present invention is the provision of a clampthe jaws of which 'ic may snugly lit the periphery of the heel andsqueeze the same while nails are driven for attaching a layer of leatherto the heel for preventing splitting of the heel during the process ofdriving nails thereto.

'15 Another object of the present invention is the provision of a clampof the character indicated which may be constructed of comparatively fewparts, which may be easily assembled or replaced.

29 W ith the above general objects in view and other that will appear asthe nature of the invention is better understood the same consists inthe novel construction, combination and arrangement of parts hereinaftermore fully described, illustrated in the accompanying drawing andpointed out in the appended claims.

in the drawing forming a part of this ap plication, and in which likedesignating characters refer t0 corresponding parts throughout theseveral views,

Fig. 1 is a top plan elevational view of the device, partly in section,showing its operative position upon the shoe heel;

Fig. 2 is a side elevational view of the clamp, partly in section, whilethe same is in an operative position upon the shoe heel; and

Fig. 3 is an edffe elevational view of the spring with the jaws orclamping members at its ends.

Referring detail to the present drawing the invention includes a pair ofL-shaped frame members 10, pivotally hinged by their leg portions by pin11, in a manner whereby said L-shaped frame members 10 effect a U-shaped frame, as clearly seen on Fig. 1.

The side portions of each of said L-shaped member 1G, adjacent the freeend thereof is provided with apertures 12, which remain in substantialalinement in both of said sides.

Serial N0. 560,295.

Said apertures are adapted to receive bolt 13, which, at one of itsends, is provided with head 14 while the other end is threaded as at 15forV receiving thereon wing nut 16. Said apertures 12 are slightlylarger than the periphery of bolt 13 for permitting play of said bolt 13within said apertures 12 during the angular shiftine movement of the twoL- shaped frame members 10 upon pivot 11 at the time pressure is exertedupon sides of said L-shaped members 10 by screwing on the wing nut 16upon bolt 13. Apertures 12 adjacent head 14 may preferably be square toaccommodate therewithin square base 1T of bolt 13, by virtue of whicharrangement bolt 13 may remain stationary at the time wing nut 16 isoperated.

At the free termination of each side of L- shaped frame member 10, andon the inner face thereof, bores 18 are made for the purpose which willbe hereinafter described The invention further includes an oblong strip19 of springy resilient nature made of metal similar to that employed inclockspring. Said strip 19 is adapted to assume a U-shaped formationwhile the same is in an operative position within frame members 10 asclearly seen on Fig. 1. Rigidly mounted by soldering or by any othersuitable means atxed to said spring strip 19, at the ends and upon thesame face thereof are clamping jaw members 20, which at their free facesare suitably grooved as at 21 in order that they may snugly fit theperipheral side of the heel 22 when the device is in an operativeposition thereupon as clearly seen on Fig. 1.

Said clamping jaw members 2O may be lined by felt or leather lining 23so as to prevent injury to the heel when the clamping j aw members 20come in contact therewith.

Spring strip 19 at the opposite face thereof and at each end is providedwith relatively short swivel pins 24 which are adapted to be received bytheir outer free ends within bores 18. Said pins 24 may either beintegrally formed with clamping jaw members 20, in which event the samemay extend through suitable apertures formed in spring strip 19,

or else may directly be affixed to said spring Y strip 19 in anysuitable manner.

From the hereinabove description it will be seen that the clamp isadjustable to suit various Widths of heels. By virtue of the fact thatstrip 19 is of resilient nature easy shitting oit' clamping jaw members20 on longitudinal plane with the free ends o t L- shaped clampingmembers 10 is obtained. The swivel arrangement of said clamping jawmembers 20 by virtue of bores 18 and pins E24, Jfacilitates readyadjustment of said clamping aw members 2O to proper posi-tion Withrespect to the adjacent portions of the periphery of the heel at thetime pressure is .exerted at L-shaped frame members 10 by means of bolt13 and wing Vnut 1X6. Further, by virtue ot swivel arrangement or' pins24 at bores 18, the lshitting movement of .clamping jaw members 20,whereby they seek most natural position with relationto the periphery ofthe shoe heel at the time pressure is exerted at L-shaped frame members10, by operating wing nut 16, is facilitated.

From the hereinabove description of the construction and operation ofthe device it will be seen that when the device is in an operativeposition upon shoe heel 2 2, great amount ofpressure may be hadthereupon by said clamping jaw members, and While this pressure iscontinued, leather layer 25 may then be safely nailed to the woodenportion of the shoe heel without fear that the heel may split as is afrequent occurrence Without the aid of suitable clamping device.

Due to the tendency of strip 1 9 to open and to assume normal positionshown en Fig. 3 on outward angular shifting of the L-shaped framemembers 10, on unscrewing oi the wing nut 16, pins 24 continue to remainWithin their respective bores 18, they being forced to remain in thatposition by virtue of the resiliency of strip 19 and by virtue of itstendency to spread| out in order to assume normal position shown on Fig.3, It is also observed that diameters of bores 18 are larger than thediameters of pins 2a permitting swivelling of said pins 24C toconsiderable degree in order that clamping members 20 may fit varioussizes of shoe heels, and further that they may quickly iind the mostsuited position with respect to the heel during the process oftightening of tlie clamp by screwing on Wing nut 416.

While there is described herein a preferred embodiment of the presentinvention., it is nevertheless to be understood that minor changes maybe made therein without depart-- ing from the spirit and scope of theinvention as claimed.

What I claim as new is:

1. A device of the class described comthrough saidV frame members, a nutupon said bolt for maintaining said frame members in a relative angularadjustment, and a spring device connecting said clamping members formaintaining the same in operative position with respect to said framemembers.

2. A device of the class described comprising a pair of L-sh-aped'framelmembers pivotally connected at their leg portions to defineV asubstantially U-shaped frame, the tree ends vor" said frame membersbeing in substantially parallel relation, clamping members swivelinglypositioned upon the inner opposed faces of the free ends of said framemembers, means for angularly adjusting said frame members, andyield-able means Vior maintaining said clamping members in operativeposition with respect to said frame members, said last namedmeanspermitting shifting of ysaid clamping members on operation of said firstnamed means in all directions other than transverse with respect to thefree ends of said frame members,

8. A device of the class described comprising a pair ot iframe memberspivotally connected by one of their ends, clamping members swivelinglypositioned upon the other ends of said frame members, means forpivotally adjusting said frame members, and yiel'dable means formaintaining said clamping members in operative position with respect tosaid frame members, said last named means permitting shifting of saidclamping members on operation of said first named means in allldirections other than transverse with respect to said frame members.

In testimony whereof I aiiix my signature.
